Vår Energi has exercised a second option for the COSL Drilling Europe semi-submersible drilling rig COSL Pioneer.

The extension continues existing drilling operations and reflects ongoing cooperation between the two companies.

COSL Pioneer is designed for operations in water depths of up to 750m. The semi-submersible rig is based on the GM4000 design and is intended for harsh-environment work, including operations in the North Sea and Norwegian Sea.

The rig maintains station keeping through an eight-line mooring system or by dynamic positioning supported by six fixed-pitch, variable-speed thrusters.

Frank Tollefsen, CEO and President of COSL Drilling Europe, said the option exercise reflects cooperation between the companies and the operational efforts delivered by their teams.
